Abstract Synthetic structures mimicking the transport function of natural ion channel proteins have a wide range applications, including therapeutic treatments, separation membranes, sensing, and biotechnologies. However, development polymer‐based artificial channels has been hampered due to limitation on available models. In this study, we demonstrate great potential bottlebrush polymers as accessible versatile molecular scaffolds for developing efficient channels. Adopting configuration...
The global scarcity of high-quality solid wood resources has propelled efforts towards developing high value-added products utilizing fast-growing wood. However, the inherent low quality poses a significant challenge for its use in engineered products. In response to this challenge, study focuses on transformation larch logs into novel engineering product termed cross-laminated-thick veneers (CLTV). process involves rotary cutting 7.5 mm thick veneers, followed by hygrothermal treatment...
In this paper, two resin-filled copp-graphite brushes were prepared at the sintering temperature of 450°C and 910°C respectively. The friction wear mechanism during current-carrying process different ambient temperatures discussed. results show that stability decreases with increase temperature, changes continuously. Compared sintered brush, brush has larger pore size higher porosity. At high condition, cumulative oxidative is obvious, resulting severe commutators. low-temperature low...

This paper describes the tribological properties of carbon/carbon composites used as braking materials under various speeds, in which with three kinds microstructures were used: rough lamina (sample A), smooth B), and mixture C), respectively. Friction tests carried out through a laboratory dynamometer. Polarized optical microscopy (OM) scanning electron (SEM) to characterize microstructure worn surface. Results indicated that friction coefficient sample A reached peak value at speed lower...
Silicon carbide nanofibers grew on the surface of carbon fibers a unidirectional preform by CCVD and then chemical vapor infiltration was used to densify obtain SiCNF-C/C composites. The effects friction wear properties composites were deeply analyzed. Results show that are well improved due melioration microstructure after modified SiCNFs. coefficient is more stable along with speed than C/C composites, it maintains high even at speed. much lower increase speed, especially in vertical direction.
Optical microscope (OM), energy dispersive spectrometer (EDS), electron backscatter diffractometer (EBSD), electrochemical test, and transmission (TEM) were employed to conduct interface microstructure observation cladding corrosion resistance analysis on 304 SS/CS clad plates that have four different reduction ratios. The increase in rolling ratio leads larger grain size, gradually refined microstructure, a decreased thickness of the interfacial martensite area. As concentration disparity C...
In this paper, sodium chloride(NaCl) was used as the separator agent and pore-forming agent. Nickel porous materials were prepared by sintering nickel oxalate(NiC2O4) NaCl after blending reduction. The pore micro morphology, porosity, size, size distribution permeability coefficient of at different temperatures studied. results show that a can effectively prevent numerous direct contacts between initial particles then reduce agglomeration during process blending. Thus, uniformly mixed...
